2 Overview Using smartphones and tablets to introduce geospatial data to students 1. Rationale. 2. Basic-level tools to use to introduce geospatial data. 3. Case Study: Geotagging photographs in student fieldwork. 4. Limitations of Geotagging 5. Geotagging: Sideshow or Saviour?

3 1. Rationale Geospatial data & analysis present and ubiquitous in everyday life. Forer & Unwin (1999) asked: Education vs. training? What is the purpose of the teaching? Is it the underlying science or the ability to drive a GIS that matters? Boyes (2011) argues that GIS classes can simply become a training exercise of knowing which button to push rather than understanding the concepts of spatial analysis and geographical information data.

4 1. Rationale Spatial Data & GIS theories (Education) Practical: Handouts, guidance (Training) = Frustrated Students: Focus is on technical problems rather than the problem-solving exercise Support Classes Quirks of the Software (vital part of the experience) Message Lost?

5 2. Introducing geospatial data

6 3. Case Study: Geotagging Photographs Geotagging is essentially adding spatial metadata to any digital media e.g. a photograph, video or microblog update. Previously geotagging required a GPS and camera plus another piece of software to sync the two pieces of equipment, generally using the date/time information. Since 2007 massive explosion in smartphones e.g. iphone, Samsung Galaxy etc. which have inbuilt GPS and automatically geotag images. Smartphone ownership is becoming ubiquitous and students are becoming more aware of geospatial data. US News and World Report listed geotagging your photos as one of the 50 Ways to Improve Your Life in 2009 (LaGesse, 2008) Welsh, K.E., France, D., Whalley, W.B., Park, J.R (in press.) Geotagging Photographs in Student Fieldwork, Journal of Geography in Higher Education.

7 3. Case Study: Geotagging Photographs Photography (e.g. Sidaway, 2002) Reflective Diaries (e.g. McGuinness & Simm, 2005) Students look with intention (Sanders, 2007 p.181) Students can re-visit the images of a landscape allowing further reflection Critical reflection & annotate images Can facilitate deep learning Geotagging can bring photography, reflection & spatial awareness together Welsh, K.E., France, D., Whalley, W.B., Park, J.R (in press.)

8 3. Case Study: Geotagging Photographs A group of first-year undergraduate geography students used geotagging photographs as one method of data collection as part of an assessed field course in Slapton, Devon. The students wanted to show evidence of increasing house prices along an 8 km transect from an inland location (Kingsbridge, Devon) to a coastal location (Slapton Sands, Devon). Geotagging was an ideal method to collect data for this project and provided students with visual and spatial data to use in their assessed report.

9 Students had: 3. Case Study: Geotagging Photographs a basic introduction to spatial data & data visualisation. grounding in rudimentary concepts of Geographical Information Systems (GIS) (despite no previous experience). a key skill (Student B) which they felt sure they would use again (Student B). a skill to could demonstrate to employers. The students stated that although the technology was basic, the same ideas could be applied with more sophisticated industry standard technology (Student A). saved time using the technology and therefore had more time to analyse the data and use higher-level skills.

11 4. Limitations Geotagging positioning system on smartphone not as accurate as GPS receiver. Accurate to several metres. Not every student has a smartphone or tablet. Not every institution has funds for smartphones or tablets (particularly for large groups). Basic introduction with basic software need to build on student s understanding with more technical details later on in the degree course.

12 5. Geotagging: Saviour or Sideshow? Saviour TRAINING VS. EDUCATION both are important, tools out there now which can introduce important concepts and familiarise students with basics before moving on to the technical aspects of spatial analysis. Hardware (i.e. smartphone or tablet) is user-friendly and potentially seamlessly integrated into every day life. Students are familiar with smartphones and locating themselves on maps using inbuilt GPS. The student focus moves away from the technological difficulties and a pushbutton training exercise and remains on the education of how to use and analyse geospatial data.
